WATER-PURIFYING APPARATUS.

i Application filed February 2 To all whom it may concern:

Be it known that l, CHARLES P. VAN GUNDY, a citizen of the United States, residing atCatonsville, in the county of Baltimore and State of `h'l'aryland, have invented certain new and useful Improvements in W'ater` Purifying Apparatus, of which the following is a specification.

My invention' relates to Water purifying apparatus of they type wherein a determinate .quantityof chemical is introduced into the water so that the impurities therein are precipitated or neutralized according to the result desired and chemicals used.

`top of a settling tank linee- 4 of Fig. 3.

The invention consists in an improved device `wheieby the amount of chemical introduced is varied according to the variations in the Water supply.

My invent-ion will be understood from the following description taken in connection With the accompanying drawings in which similar reference characters indicate' the same arts in the several figures of drawing and `W iereinz j Figure 1,is a central vertical section showing my improved. apparatus mounted on the g Fig. 2, is an elevation showingzthe parts of the device on an enlarged scale; Fig. 3, is a central vertical section similar to Fig. 1, showing a 'jnetlified form ofthe device,- andFig. 4, is a"vle\v on 1 designates a settling tank equipped in any suitable manner with. flushing valves, filter and' overflow and having in the present instance a central pipe therein which may i have suitable openings into the tank in the lower part thereof (not shown).

The tank 1 may have overflow 3 and a filter 4 of excelsioij or the like. A suitable perforated bafiie 5 and a conical funnel (i may be provided at the top of said pi )o 2 for the admission of water thereinto. T ie water supply pipe 7, delivers into a mixing box 8, mounted `on top of the tank and havin g a suitable vertical outlet Vslot 9 adjacent to the funnel l. Suitably pivoted at 1() above and adjacent to the mixing box S is a' chemical box or holder 11. This box or holder has an opening or slot 12 adjacent the mixing box, the arrangement being such that upon the tilting i the amount of tilting, through the slot 12 into the' mixing box S. The slot 12 is preferably adjustable as to Width; a preferred means for Specification of Letters Patent.

effecting such adjustment is to have'an adregulate by suitable backing screws 14 which screws may be threaded through a rib '15 on the box. Another opening or slot 16 is formed in the end of the box 11 opposite the slot 12 for a purpose hereinafter explained. j

Pivoted at 17, upon a suitable standard is a lever 18, said lever having a pivoted connection 19 at its remote end to the rod of a float 20. Said float may be guided in a perforated cylinder 21 suitably arranged in the mixing box 8. 'Bhe lever 18 has a connection at 22 with the box 11 at a point. diagonally opposite the pivot 10 or approximately so. lA chemical pipe 24 is arranged to deliver into the chemical box 11. By a forcing device (not shown) or other means a constant flow of chemical is fed through the pi e 24 somewhat in excess of what is normal y rec uired for treating the Water as supplied by t ie pipe 7. `A chemical return pipe 23, whic i may have a funnel at Iits top is arranged directly underneath the opening or :not 16. A

understood from the foregoing description. .When the pipe 7 delivers a larger quantity of water than usual, the water level in the mixing'chamber 8 rises, thereby lifting the float 20. This float by the connections 19 and 22 thereof with the chemical box 11 will cause said box to be tilted to agreater extent,jthus emptying a correspondingly larger proportion of the chemical therein into thebox S and permitting a smaller' proportion thereof to return by the opening or slot 16 and i e 23. 'hen the volume of water supplie gy pipe 7 falls below normal the reverse operation takes place, the box 11 assuming more nearly a horizontal position, and hence a llarger proportion of chemical will be discharged by slot 16 into the return ipe 23 and a smaller amount will be adde to the water.

The opening or slot 12 in the chemical box l1 is preferably made adjustable in width as described so that a )redetermined ratio between its volume o discharge and that of the opening or slot 9 ii. box 8 may be mainor slot 12 is widened a larger proportion of chemical will be introduced volume of water.

The lever 18 maybe provided with a suittained, it being obvious that as the opening.

In this modification the iioat 2O is 'spensed with and the inixingbox itself is vvertically movable', being mounted The chemical box 11 is ivtek upon standards 11 and is tilted in 'ke manner as in the preceding case by lever 1 8- and connections 22, 19 and`19,.
